How add "#" to blank lines when using py-comment-region???

How add "#" to blank lines when using py-comment-region???

[Christian Seberino]

py-comment-region lets me 
add "#" at beginning of non-blank lines that I have
highlighted with mouse.

It does not add "#" for the blank lines.

How can I modify behavior of py-comment-region to do this?

py-comment-region is just a minor wrapper around comment-region,
so the variable you want to look at is comment-empty-lines.

If you only want to comment blank lines in python mode, you'll
have to make comment-empty-lines buffer local and set it in a
hook.

Thanks for the help.  comment-region is a powerful command useful in
all languages!  I tried to set comment-empty-lines but could not
get blank lines to get commented.

Here is a small .emacs I made to try to comment empty lines when
I do a comment-region command.  It works except for blank lines
in C...

   (setq-default auto-mode-alist
      '(("\\.c\\'"    . c-mode      )
        ("\\.h\\'"    . c-mode      ) ))

   (add-hook 'c-mode-hook 'my-c-mode-hook )

   (defun my-c-mode-hook()
      (turn-on-font-lock)
      (setq comment-empty-lines t) )


What am I doing wrong?
Thanks!

Chris
